No timezone in environments timestamps

I'd like to see the timestamp for this deployed_at time with a timezone.

What I see

It currently looks like this (in environments section of an MR Pipeline):

The code that generates this timestamp uses the timeago_mixin

What I'd like to see instead

The timestamps in the notes section of an MR include a timezone, which is what I'd like to see here. Example:

system note HTML is coming from application_helper.rb. For the system note timestamp, the datetime in HTML is UTC and then the title is in my local timezone. I'd love the same for the javascript timestamp:

<time title="May 23, 2023 6:20pm GMT+0800" datetime="2023-05-23T10:20:13.520Z" class="">18 hours ago</time>
